The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening. If the USB device does not work after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power. If used with PCI Express Gen 2.0 enabled computers, the max throughput is 5 Gbps. If used with PCI Express Gen 1.0 enabled computers, the max throughput is 2.5 Gbps. The maximum throughput of this card is limited by the bus interface.
Test results were obtained using an Intel® Ivy Bridge system, add-on USB 3.0 cards, a UASP-enabled enclosure, and a SATA III solid state drive. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.Īt the same peak in testing, UASP also showed up to an 80% reduction in required processor resources. UASP is supported in Windows® 8, Server 2012 and Linux kernel 2.6.3 or later.

For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.īacked by a 2-year warranty and free lifetime technical support. With a built-in SATA power connector, each USB port can provide up to 900mA of power to USB 3.0 devices (500mA for USB 2.0) by connecting to your computer power supply. See our UASP test results below for further details. Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. With SuperSpeed USB 3.0, you can reach data transfer speeds up to 5 Gbps, while still being backward compatible with existing USB 2.0 devices at 480Mbps.Įnhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a External Drive Enclosures (Note: UASP requires a compatible operating system). The PEXUSB3S4 4-Port PCI Express SuperSpeed USB 3.0 Card (with SATA Power) adds 3 external USB 3.0 ports and an internal USB 3.0 port to any PCI Express-enabled computer system.
